We suspect changes in FreeBSD 11, but these are unsubstantiated and / or do not cater to FreeBSD use cases so nobody fixes them there. Or Nano although derived from NanoBSD does not seem to be used that often anymore over there. Or our tooling is completely wrong here. In any case, there is not much movement from here as we try to spend our time fixing the things in OPNsense which is more "bang for the buck". :)
